You cannot do it as it need a specialist's skill.What i do is to insert a bubble tea's drinking straw and insert it into a vacuum cleaner's attachment that is formed like a **** and attach the other end into the grills of the device and gently vacuum the dust away.Good luck.

I picked up a Sunbeam Humidifier model 1118 for $7 (which was $7 too much) second hand. It wasn't until I got home that I noticed it was filthy-dirty inside...(dirtier than shown in the photos) the reservoir, the bottom tray, AND the fan chamber all needed major cleaning.

A quick Google search told me that the grill is "not removable", and the unit is "not user serviceable". Companies do this/say this for two reasons:

a) They want you to throw it away and buy a new one, landfills and plastic filling our oceans be darned b) They want to protect themselves from lawsuits, should someone injure themselves servicing their product (or in this instance, cutting their fingers off on the fan blade).

Imagine if all of that design know-how was put into making the product serviceable, cleanable, and long-lasting, rather than ensuring it can't be opened or repaired by the average joe.

Me, I've opened and repaired enough gadgets to think differently.

You CAN remove the grille. Carefully insert a series of flat-head screwdrivers between the grill and the body a few inches apart, wedging the grill edge away from the body. There are slits in the body (see photos) that will allow you to get under the grill edge and pry it right out when enough of it has been detached from the anchoring groove. But be gentle while you're doing it. The Grille is plastic and flexible; it will bend, but if you use too much force you will damage either the grill or the body.

The photos also show how the grill is anchored to the body - via a groove in the grille edge.

You can put the grille back after cleaning the blades and fan chamber much the same way; pressing down, and if required: prying the side of the grill inwards with a flat head screwdriver.Mine snapped right back into place with a bit of downward pressure.

According to the Owners Manual, there's no way remove the top covering the fan. Just clean with a damp cloth and then wipe it draw. However, before wiping it with a damp cloth, you may want to try blowing out the sections of the grill with some canned compressed air with a straw nozzle (like you clean your computer with). Or use a vacuum cleaner with a hose and brush attachment. After doing that, wipe with a damp cloth and then a dry cloth.

Here is a solution I wrote up for another Humidifier with a fan problem:

Have you considered checking to see if the fan motor mightjust need cleaning and lubricating? Most small fans and heaters, have small fan motors, in which thebearings have dried out over the years. If you have made anelectrical check on the motor leads-- and you have electric going into thewindings, likely the motor feels warm? (If not-- possibly a bad splicewhere the supply wire attaches to the tiny armature wires?-- check , and checkcontinuity)

If you want to tear into the fan motor, and clean up and lubricate thebearings-- here are some tips:

First you need to get inside the heater of the fan housing-- by removing theprotective covers. Note the screws, s, locations, and how the protective coverswill go back on when you are ready to reassembly-- Mark where the screw holesare that line up with the matching other parts.

Then remove the motor from it's bracket (Possibly have to remove the fanfirst?) You will have to remove the fan, to lubricate both front and realbearings. Next you will need to remove the 4 long screws that hold the motorframe together-- Be sure to mark the original alignment, so you can reassemblycorrectly.

Now, with the fan removed, gently separate the Front and rearhalf's of the motor. Usually the windings will stay with the portion ofthe motor where the wires are still attached. Either way, you are goingto have to get the bearings to slide off both Shafts of the armature-- withoutbreaking the delicate winding wires-- the wires are hair thin on small motors!

Now clean up the caked on residue on the shaft where the bearings ride,with rubbing alcohol. Clean up the internals of the bearings as best youcan- making sure the pores of the oil-lite bearings are not plugged withsolids. Now begin the gentle process of getting the bearing wicking tosoak up new oil. When you are sure the reservoirs are wellsaturated, then generously lubricate the shafts, and slip them thru thebearings again-- retracing all your steps above, The motor shaft shouldturn freely now. You can test the motor without the fan on-- to besure you have the motor itself reassembled properly.

Double check all the splices, switches, and any high temperature limit switchesfor continuity-- and trace the wiring all the way back out thru the powersupply cord.

This sounds like the electric motor bushings are worn which will cause vibration throughout the unit. If it is relatively new I recommend checking the warranty information and returning it to the retailer for a replacement. If you have gotten your money out of it but cannot tolerate the noise, then a replacement is in order as well. The cost of replacing the motor and installing it will most likely exceed the cost of a new humidifer.

you have to pop the cover off of the top if there are not screws holding the cover on then it should pop off with a screwdriver or you can use compressed air in a can that they sell in stores for cleaning computers

Make shure that the the filter in the bottom of the valve is clean. Turn water off use a 1/2 & 7/16 wrench to take apart the bottom connection on valve use a small screwdriver and push the small screen out and clean then put it back together.Use the same wrenches and take apart the top of valve clean inside valve and clean small orfice in plastic water line put back together. Make shure 24volts is gettin to valve you should her a click when furnace is running or fan. It may take a couple times to clean. Hope this helps

No. when you remove the front cover it will automatically disconnect the power supply. Try changing the water panel and cleaning out the orifice and filter screens located in the water lines connected to the solenoid valve.

If you email me at jennju@hotmail.com, I can send you a pdf of the manual for this product. I had the same model and was able to remove the fan cover by slightly twisting it and pulling up -- was able to clean the unit very well once I removed the cover! good luck...

A noisy humidifier may be the result of an unlubricated fan motor or a drive mechanism clogged by debris. Periodically clean the water reservoir, fan, and nozzle to ensure that they are clean and working properly. To keep your humidifier working smoothly and efficiently, lubricate the fan motor bearings with SAE #20 oil. Be sure to consult your owner?s manual for proper care and maintenance procedures.
If it seems loose, vibrating parts are causing the noise:
1) Disconnect the power.
2) Remove the cover and look for any vibrating parts. Tighten screws, if necessary.
3) Wiggle the fan to see if it is loose on its shaft. If it is, tighten the mounting fasteners. Lubricate the motor's bearings if suggested in your owner's manual.
4) If it still makes noise, call an appliance repairperson or take the unit into an appliance repair shop.
